Amazon Fleece Size: XS Fits approximately 4-5 year olds, around 110cm. I took a picture comparing it with a Uniqlo 110 I'm also selling. The length and sleeves are longer than Uniqlo, and the arms are slimmer. I bought this thinking my daughter would wear it under her kindergarten uniform, but she preferred something else and wore it constantly, so this one was only tried on and she outgrew it. It's a dark navy blue, so it will match a uniform.
